Definitions

  • the invention relates to a brazed heat exchanger, in particular a condenser for motor vehicles with at least one collecting tube and a flange attached to the manifold for receiving connecting pipes according to the preamble of claim 1.
  • a brazed heat exchanger in particular a condenser for motor vehicles with at least one collecting tube and a flange attached to the manifold for receiving connecting pipes according to the preamble of claim 1.
  • US 2003/6173069 A1 discloses such a heat exchanger.
  • the condenser consists of a tube / fin block and laterally arranged collecting pipes.
  • the known capacitor also has a connection flange for connection of refrigerant lines of a refrigerant circuit.
  • the connecting flange is connected by means of a holding plate via rivets or screws with the tube / fin block of the capacitor.
  • a connecting pipe for the refrigerant inlet is arranged between the connection flange and a manifold.
  • the connection flange is connected to a refrigerant outlet pipe of the condenser.
  • the attached to the condenser flange thus represents the interface to the refrigerant circuit of the motor vehicle.
  • the disadvantage is the attachment by rivets or screws in the tube / rib block, which can lead to damage or leaks.
  • additional assembly steps for the attachment of the retaining plate on the tube / rib block and the connecting flange on the holding plate required.
  • Such refrigerant condensers consist essentially of aluminum parts, which are soldered together to form a finished heat exchanger.
  • the goal and at the same time problem in the soldering is to position and fix all parts to each other so that they can be soldered in the brazing furnace without additional Löt Anlagen or soldering or as few such devices.
  • connection flange is a heat exchanger, in particular a soldered refrigerant condenser described with at least one collecting tube to which a connecting flange can be fixed and soldered.
  • the connecting flange is preferably produced by extrusion and has a one-piece holder which clampingly surrounds the collecting tube and forms a soldering surface with the latter.
  • the connection flange is connected to the manifold via two connecting pipes for the refrigerant inlet and the refrigerant outlet. In this position, the capacitor is soldered together with connecting tubes and flange. It thus has a common flange for connection to a refrigerant inlet and outlet line of a refrigerant circuit. Due to the integral formation of holder and flange as an extrusion part, the connection positions are limited.
  • the flange is laterally offset relative to the manifold or the block consisting of tubes and ribs.
  • installation height or width can be saved when installing the capacitor.
  • the lateral arrangement is achieved in that the holders have transversely to the collecting tube projecting retaining arms on which the connecting flange is held.
  • the connecting flange on one or more holding lugs which advantageously have guide and retaining grooves.
  • the holders themselves are inserted into corresponding slots in the manifold and caulked there by flags (approaches to the holders).
  • flags approximately to the holders.
  • the holders are fixed to the headers.
  • a further fixation of the connection flange takes place through the connecting pipes, which are inserted on the one hand into corresponding openings in the collecting pipe and on the other hand are inserted into connecting openings in the flange.
  • connection flange can be produced by extrusion or extrusion - so that the manufacturing costs be lowered; however, the blank is subsequently machined, ie milled and drilled. It is thus also possible to realize deflections of the refrigerant within the flange by 90 degrees.
  • the flange in its raw form can also be made by forging or casting.
  • Fig. 1 shows a condenser 1 of an air conditioner, not shown, for a motor vehicle.
  • the condenser has a block 2, consisting of unspecified flat tubes and corrugated fins, with an end face 2a, wherein the flat tubes open with their ends in laterally arranged manifolds 3, 4.
  • the condenser 1 flows through the primary side of refrigerant of a refrigerant circuit, not shown, and connected via a connection flange 5 to the refrigerant circuit.
  • the connecting flange 5 is connected via a first connecting pipe 6 for the entry of the refrigerant to the upper part of the collecting tank 3 and via a second connecting pipe 7 for the exit of the refrigerant from the condenser 1 to the lower part of the collecting pipe 3.
  • the condenser 1 is in the position shown, ie installed with approximately horizontally arranged tubes or vertically arranged manifolds 3, 4 in the vehicle and fastened there via tabs 8.
  • Fig. 2 shows an enlarged section Fig. 1 with the connection flange 5, which is attached to the manifold 3.
  • the connecting flange 5 serves for the refrigerant side connection of the condenser 1 to the refrigerant circuit, not shown, of the motor vehicle air conditioning system and thus constitutes an interface.
  • the flange 5 therefore has four openings for the passage of the refrigerant, namely a first connection opening 9 for the entry of the refrigerant (from the refrigerant circuit) and a second connection opening 10 for the exit of the refrigerant (in the refrigerant circuit), further comprises a connection opening 11 for receiving the connecting pipe 6 and a connection opening 12th for receiving the connecting pipe 7.
  • the connecting pipe 6 opens into a non-illustrated inlet chamber of the manifold 3 and the connecting pipe 7 in a likewise unspecified outlet chamber of the manifold 3; the subdivision of the headers in chambers by partitions is known from the prior art.
  • the connection openings 9, 10 are closed by plugs 9a, 10a for the transport of the condenser 1 - they are removed when connecting the condenser to a counter flange, not shown, of the refrigerant circuit.
  • the fastening eyes 9b, 10b arranged adjacent to the connection openings 9, 10 serve for fastening the abovementioned counter flange, which is not shown, which is generally a standard part.
  • the connecting flange 5 also has two retaining lugs 13, 14 with guide and retaining grooves 13a, 14a. At the collecting tube 3 are two transversely to the longitudinal direction of the manifold 3 horrrekkende holder 15, 16 attached, which are received by the grooves 13 a, 14 a of the attachment lugs 13, 14. About the holder 15, 16 of the connecting flange 5 is substantially fixed relative to the manifold 3 and - after soldering - fixed, with an additional fixation and attachment is also on the two connecting pipes 6, 7 given.
  • Fig. 3 shows an exploded view of the parts to be joined before soldering, namely the manifold 3, the two holders 15, 16, the two connecting pipes 6, 7 and the connecting flange 5 with the attachment lugs 13, 14.
  • the same reference numerals as in FIGS. 1 and 2 used.
  • the connection flange 5 can initially be produced, ie as a blank by extrusion.
  • the two retaining lugs 13, 14 with their guide and retaining grooves 13a, 14a typical extrusion profiles, which do not extend over the entire depth of the connecting flange 5, however.
  • the extruded blank of the connecting flange 5 is therefore - to the Fig. 3 apparent form to receive - additionally subjected to a cutting machining such as drilling and milling.
  • the two holders 15, 16 are of identical design and have at their end facing the manifold 3 a downwardly directed approach, a so-called flag 15b, 16b and at its opposite end in each case a holding arm 15a, 16a.
  • two slots 16, 17 are arranged at the top, in which the flags 15a, 16a of the holder 15, 16 are inserted and caulked from the inside.
  • a fixation of the two holders 15,16 is achieved with respect to the manifold 3.
  • connection flange 5 On the thus fixed holder 15, 16 of the connecting flange 5 is inserted by the holding arms 15 a, 16 a are inserted into the guide and retaining grooves 13 a, 14 a, up to a stop on the holder.
  • the connecting pipes 6, 7 are inserted into corresponding unspecified openings of the collecting pipe 3 and at the same time into the connecting openings 11, 12.
  • solder rings 19, 20 are provided, while the holders 15, 16 are soldered on both sides to solder on the one hand to the manifold 3 and on the other hand to the connection flange 5.
  • connection flange 5 is fixed to the manifold 3, that is, the capacitor 1 connected.
  • the connecting tubes 6, 7 are soldered tight in both the manifold 3 and in the connection flange 5 and the slots 17, 18 are sealed by soldering the holder 15, 16.
  • the connecting flange 5 has a front planar connecting surface 21, which approximately parallel to the end face 2a (see. Fig. 1 ) is aligned and connected to a counter flange, not shown, for connection to a refrigerant inlet and - outlet line.
